Chap 2 - 4 Flashcards
1
Q
Acceleration formula
A
a=(v-u) / t
acceleration(m/s²)=
(end speed-initial speed) /time
2
Q
Distance?
A
Area under Speed-Time graph
D=Speed*time
3
Q
Pressure formula
A
P=F/A
Pressure(Pa)=Force(N) / Area(m²)
4
Q
Force formula
A
F=ma
Force(N)=mass(kg) * acceleration(m/s²)
5
Q
When speed is constant, what is resultant force
A
resultant force = 0
6
Q
What is Newton’s Third Law?
A
Every action has its equal opposite reaction
7
Q
Resultant Force Fomula
A
Fr = force in same direction - force in opposite direction
